Land Area Calculator & Converter & Acre · Hectare · Bigha · m²
Converts acre ↔ hectare
Work out a plot's area from its shape, or convert any value instantly between acre, hectare, m², ft², bigha, guntha, cent, are, marla and kanal — the starting point for every farm calculation.
Computed area: 5,000 m². For odd-shaped fields, split into rectangles and triangles and add them up.
Your plot is about 1.24 acre (0.5 ha · 5,000 m²). Use this to size seed, fertilizer, irrigation and labour to the real area.
Next: most farming calculators here take an area — plug this figure into seed-rate, fertilizer, yield and profit tools to scale everything correctly. Bigha varies by region; this uses the common North-India pucca bigha.
Local units like bigha, marla and kanal vary by region — confirm the local definition for legal or sale purposes.

Get the area right before anything else
Area is the foundation of farm planning — seed, fertilizer, manure, irrigation water, yield and profit all scale with it, so an error here multiplies through every later calculation. This tool does two jobs. From a shape and dimensions it computes the area of a plot (rectangle, triangle, circle or trapezium), and as a unit converter it turns any value between the eleven land units farmers actually use, from the international acre and hectare to local bigha, guntha, cent, marla and kanal.
That matters in regions where land is bought in bigha, taxed in hectares and planned in acres all at once. Compute or convert once here, then carry the figure into the seed-rate, fertilizer, yield and profit tools so everything lines up. For odd-shaped fields, break the plot into simple rectangles and triangles, add the parts, and remember that traditional units vary locally — confirm the regional definition for any official transaction.

Frequently Asked Questions
How do I calculate the area of my field?+
Pick the shape closest to your plot and enter its dimensions in metres — length × width for a rectangle, ½ × base × height for a triangle, π × radius² for a circle, or ½ × (a + b) × height for a trapezium. The tool computes the area and converts it to every land unit. For irregular fields, split them into rectangles and triangles and add the parts.
How many square feet are in an acre?+
One acre is exactly 43,560 square feet (4,046.86 m²). The tool shows this and every other conversion the moment you enter a value.
How do I convert acres to hectares?+
Multiply acres by 0.404686 to get hectares (1 acre = 0.404686 ha), or divide hectares by that figure to go the other way. One hectare equals about 2.471 acres.
What is a bigha in acres?+
Bigha is a traditional unit that varies by region. This tool uses the common North-India pucca bigha of about 2,529 m², which is roughly 0.625 acre (so 1 acre ≈ 1.6 bigha). Always confirm the local bigha definition for legal or sale purposes.
How many cents are in an acre?+
There are 100 cents in an acre, so one cent is about 40.47 m² (435.6 ft²). The cent is widely used in South India for small plots.
What are marla and kanal?+
Marla and kanal are land units common in Pakistan and northern India. This tool uses a marla of about 25.3 m² and a kanal of about 505.9 m² (20 marla = 1 kanal); regional definitions vary, so verify locally.
How do I measure an irregular plot?+
Divide the plot into simple shapes — rectangles and triangles — measure each, compute their areas here, and add them together. For surveyed plots, a professional measurement or GPS area is more accurate than splitting by eye.
Why does it ask for metres?+
Using metres keeps the maths consistent (a square metre is the base unit), and the tool then converts the result into every land unit including feet-based ones. If you measured in feet, convert to metres first (1 ft = 0.3048 m) or use the unit converter mode.
Why do I need the area for other tools?+
Almost every farming calculation scales with area — seed rate, fertilizer, manure, irrigation water, yield and profit. Getting an accurate area first means every downstream figure is right, which is why this tool feeds the rest of the Farming Hub.
Is the conversion exact?+
The metric and acre/foot conversions are exact, internationally defined values. Traditional units (bigha, marla, kanal, cent) have regional variants — this tool uses widely accepted figures, but check the local standard for official transactions.
